| 摘 要： | 提出了考虑支座摩擦作用的连续梁桥分析模型,利用摩擦单元对考虑支座摩擦耗能作用的连续梁桥进行了分析,分析结果表明,支座摩擦力可以较为明显地降低梁桥的地震作用。根据分析结果,对连续梁桥的设计提出了支座选用建议和抗震措施。

| Abstract: | The analytic model of the continuous bridge which including the effects of friction force at movable supports was put forward,and the analysis was done with the friction element in this paper.The results indicate that the friction force can greatly decrease the earthquake action of the continuous bridge.And some suggestion on the bearing selection and the anti-seismic measure were also put forward. |
